Background: Suicide is a major cause of death worldwide. While studies have been conducted on the predictors of suicide behaviors, these have not covered how lethality and the various predictors differ by age. We explored these age differences in the present study. Methods: We retrospectively reviewed the medical records of suicidal patients in the emergency department (ED) of a university hospital in Seoul, South Korea, between September 2017 and August 2018.We extracted participants' data fromthe National Emergency Department Information System of Korea and their individual electronic medical records (EMRs), including demographic information (e.g., age, gender), details of their ED visit (e.g., suicide method), and medical history (e.g., physical illness, alcohol co-ingestion).We also used EMR data to complete the Risk-Rescue Rating Scale (RRRS). Results: Of the 499 patients referred to the ED for suicide attempts, 427 were analyzed. We found that while younger participants were more likely to have repeated attempts, older participants' attempts were more likely to be fatal (e.g., higher RRRS risk scores and lower accessibility-to-rescue scores). After adjusting for demographics, older participants showed significantly higher scores on RRRS risk, impaired consciousness, and treatment required than younger participants. Conclusion: Our findings clarified the characteristics of high-risk suicide attempters based onage, which could influence suicide-prevention policies (e.g., younger people tend to repeat suicide attempts, and thus may require continued surveillance). However, as older adults showed higher lethality and were more difficult to save, they may require suicide prevention coupled with social support interventions. [ABSTRACT FROM AUTHOR]

Two American Cocker Spaniels and one Bichon Frise were presented to our veterinary teaching hospital with an enlarged clitoris. Diagnostic imaging showed that the structure was composed of bony material. Exploratory laparotomy revealed uterine-like structures and testes which had an epididymis unilaterally. Surgical removal of internal genitalia, gonads and protruded clitoris were performed well. Histological evaluation revealed; inactive testes, female internal genital tracts with ambisexual ductal remnants, and prominent ossification in the clitoris. All 3 cases were diagnosed with male pseudohermaphroditism. In author's knowledge, this is the first report in Bichon Frise dog with os clitoris and also, it describes not common cases in small dog breeds with os clitoris. [ABSTRACT FROM AUTHOR]

Extrapleural solitary fibrous tumor, formerly referred to as "hemangiopericytoma" is a rare soft tissue vascular tumor which has elevated malignancy potential arising from the capillary pericytes. Extrapleural solitary fibrous tumors, originating from the spleen, are extremely rare. We rep ort on a rare case of a patient presenting with splenic extrapleural solitary fibrous tumors with intratumoral irregular calcification detected by dynamic contrast-enhanced computed tomography.

The debris generated by the explosion of a building or ammunition is flown far away through the ricochet phenomenon. The debris contains a very large amount of energy, and a risk factor surrounding it may be applied. The safety distance from debris is set from experiments or FEM analysis. The ricochet of debris is affected not only by the initial conditions of the debris, but also by the conditions of the medium. In this paper, the effect of sand temperature on the ricochet of sphere projectiles was investigated through experiments and FEM, by measuring the shear stress and internal friction angle when the sand temperature increases. As the temperature of the sand increases, the shear stress and the internal friction angle decrease, and the penetration depth of the projectile increases. As the depth of penetration becomes longer, the kinetic energy is lost more by the friction force with the sand and, the sphere projectile speed decreases more. This is mainly caused by the energy loss of the projectile, so the kinetic energy of the ricocheted projectile is reduced. Therefore, when setting the optimized inhabited building distance (IBD), the conditions of the medium should be taken into account. [ABSTRACT FROM AUTHOR]

Oral hygiene care (OHC) is associated with in-hospital infection. Among the many materials used for OHC, gauze is one of the most common. However, many patients receiving OHC are in a poor state of consciousness and thus at high risk of foreign-body aspiration or ingestion. Here we present three cases of unusual foreign-body obstruction that developed in cognitively impaired patients. These cases highlight the need for increased clinical awareness regarding vulnerable patients at risk of complications related to a foreign body in the gastrointestinal tract or the airway.

The article summarizes the background information for composite columns and beam-columns relevant to new provisions in the 2005 American Institute of Steel Construction Inc. (AISC) Specification (AISC, 2005b). The columns include steel reinforced concrete (SRC) and concrete-filled steel tube (CFT) members. According to the authors, AISC, 2005b include provisions for composite column axial compressive strength, local buckling strength of concrete-filled tubes, and shear strength of composite members.

Vascular injuries caused by cardiopulmonary resuscitation (CPR) can be associated with major complications. If patients who have received CPR have sudden abnormal hemodynamic findings, it is necessary to consider the possibility of these injuries. We report a 73-year-old man who had cardiac tamponade due to an injury to the internal mammary artery following manual chest compression. This very rare injury was detected by computed tomography and was treated by thoracotomy and hematoma evacuation. [ABSTRACT FROM AUTHOR]
